下面是打开设置网络的Dialog的界面

/**
     * 打开设置网络界面
     * @param context
     */
    public void showSetNetworkUI(final Context context) {
        // 提示对话框
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle("网络设置提示")
                .setMessage("网络连接不可用,是否进行设置?")
                .setPositiveButton("设置", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Intent intent = null;
                        // 判断手机系统的版本 即API大于10 就是3.0或以上版本
                        if (android.os.Build.VERSION.SDK_INT > 10) {
                            intent = new Intent(android.provider.Settings.ACTION_WIFI_SETTINGS);
                        } else {
                            intent = new Intent();
                            ComponentName component = new ComponentName("com.android.settings", "com.android.settings.WirelessSettings");
                            intent.setComponent(component);
                            intent.setAction("android.intent.action.VIEW");
                        }
                        context.startActivity(intent);
                    }
                }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        }).show();
    }
